Dicor takes a long time to cure totally. Go have a look in about a month and you will be surprised at how much it has tightened up. I have used alcohol to clean area, mineral spirits/ paint thinner/ varsol to wet finger & tool with no problems at all. Try to buy Dicor from dealer that sells lots of it tho. I got a tube of " self leveling" once that must have been old, because it behaved like "non sag" when i applied it, and stayed blobby instead leveling its self. I use non sag between roof & object to seal, then self leveling on top for screws heads and edges etc.
